Apr 24, 2013 · I read this line in the Java tutorial: byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters.

In Sun' tutorial it says about a byte: byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters.

A Java byte is a primitive with a minimum value of -128 and a maximum value of 127 (inclusive). 87 is within the allowed range. The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters. A byte[] is an Object which stores a number of these primitives.

no of values data type can have=2^n(2 power n), where n represents no of bits. so the value of byte data type=2^8(i.e 1 byte=8 bits),here n=8 byte value=256. And it should be shared equal on both sides of zero ( half values at negative and half value at positive ). Hence the range for byte is from -128 to 127.

Without getting into two's complement: 2^8 (since a byte is 8 digits and can have 1 of 2 values) = 256, so the most individual values a byte can represent is 256. so, representing the numbers -128 to -1 is half our range. I believe the question here is …

byte is a 8-bit signed primitive-type in java. It is usefull in the situations where we are dealing with the data in the form of bytes such as "Reading/writing the byte data from/to files". You can find the best practical example at here.

Mar 4, 2011 · You can use a byte literal in Java... sort of. byte f = 0; f = 0xa; 0xa (int literal) gets automatically cast to byte.

Jun 26, 2012 · Hex.decodeHex(char[] data) which throws a DecoderException if there are non-hex characters in the array, or if there are an odd number of characters. Hex.encodeHex(byte[] data) is the counterpart to the decode method above, and spits out the char[]. Hex.encodeHexString(byte[] data) which converts back from a byte array to a String.

Oct 26, 2010 · A byte is 8 bits (binary data). A byte array is an array of bytes (tautology FTW!). You could use a byte array to store a collection of binary data, for example, the contents of a file. The downside to this is that the entire file contents must be loaded into memory.
